Chris Collins lost his mind and got a costly tech with under five minutes to go in Northwestern’s loss to Gonzaga in the second round of the NCAA Tournament on Saturday over a missed goaltending call.

Northwestern center Dererk Pardon went up for a lay in late in the second half and had his shot attempt rejected by Gonzaga freshman Zach Collins. The referees missed that Collins had reached his hand all the way through the cylinder to block the shot and that goaltending should have been called.

Northwestern’s coach was livid over the missed call and ran onto the court in protest. He was quickly given a technical foul.

Gonzaga’s Nigel Williams-Goss made both his free throws to make it 65-58 in favor of the Bulldogs. If the goaltending were correctly called, the score would have been 63-60 and a 3-point game instead of a 3-possession game.
